Description

FIELD OF THE INVENTION

The present invention relates to a power supply apparatus, and more particularly to an intelligent power supply apparatus.

BACKGROUND OF THE INVENTION

Power supply apparatuses are essential for many electronic appliances such as personal computers, industrial computers, servers, communication products or network products. Usually, the user may simply plug a power supply apparatus into an AC wall outlet commonly found in most homes or offices so as to receive an AC voltage. The power supply apparatus will convert the AC voltage into a regulated DC output voltage for powering the electronic device and/or charging a battery built-in the electronic device.
Generally, power supply apparatuses are classified into two types, i.e. linear power supply apparatuses and switching power supply (SPS) apparatuses. A linear power supply apparatus principally comprises a transformer, diode rectifier and a capacitor filter. The linear power supply apparatus is advantageous due to its simplified circuitry and low fabricating cost. Since the linear power supply apparatus has bulky volume, the linear power supply apparatus is not applicable to a slim-type electronic device. In addition, the converting efficiency of the linear power supply apparatus is too low to comply with the power-saving requirements. In comparison with the linear power supply apparatus, the switching power supply apparatus has reduced volume but increased converting efficiency. That is, the switching power supply apparatus is applicable to the slim-type electronic device and may meet with the power-saving requirements.
For normal operations of the linear or switching power supply apparatuses, stability and reliability are very important factors. After the power supply apparatus has been used for a certain period, some components included in the power supply apparatus are possibly malfunctioned or damaged and thus the power supply apparatus eventually has a breakdown. Conventionally, the user doesn't realize the breakdown of the power supply apparatus until the power supply apparatus fails to be operated. In addition, even the maintenance worker needs equipment or a troublesome testing procedure to realize whether the operating conditions of the power supply apparatus are unstable.
There is a need of a providing an intelligent power supply apparatus to obviate the drawbacks encountered from the prior art.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an intelligent power supply apparatus whose operating statuses may be easily realized by periodically generating operating prompts.
Another object of the present invention provides an intelligent power supply apparatus capable of generating warning prompts to notify the user of the malfunction of the intelligent power supply apparatus.
A further object of the present invention provides an intelligent power supply apparatus communicable with an external processing device so as to transmit output audio signals to the external processing device.
In accordance with an aspect of the present invention, there is provided an intelligent power supply apparatus. The intelligent power supply apparatus includes a power converting circuit, one or more sensors, an audio processor, an operating status processor, a storage unit and a loudspeaker. The power converting circuit is used for converting an input voltage into a regulated DC output voltage. The sensors detect operating statuses of the intelligent power supply apparatus, thereby generating corresponding sensing signals. The audio data are processed by the audio processor. The operating status processor is electrically connected to the sensors and the audio processor for controlling the audio processor to generate corresponding output audio signals in response to the sensing signals. The storage unit is electrically connected to the audio processor and/or the operating status processor for storing therein audio data. The loudspeaker is electrically connected to the audio processor for generating audio prompts corresponding to the output audio signals.
In accordance with another aspect of the present invention, there is provided an intelligent power supply apparatus. The intelligent power supply apparatus includes a power converting circuit, one or more sensors, an audio processor, an operating status processor, a communication interface and a storage unit. The power converting circuit is used for converting an input voltage into a regulated DC output voltage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only. It is not intended to be exhaustive or to be limited to the precise form disclosed.
FIG. 1 is a schematic circuit block diagram illustrating an intelligent power supply apparatus according to a first preferred embodiment of the present invention. The intelligent power supply apparatus 1 of FIG. 1 principally comprises a power converting circuit 11, several sensors 12, an audio processor 13, an operating status processor 14, a storage unit 15 and a loudspeaker 16. An input voltage Vin (e.g. an AC voltage or a DC voltage) is received from an input end 11 a of the power converting circuit 11. By the power converting circuit 11, the input voltage Vin is converted into a regulated DC output voltage Vout required for powering a load (e.g. an electrical appliance or a motherboard of a computer system). By detecting operating statuses of the intelligent power supply apparatus 1, the sensors 12 issues corresponding sensing signals. Examples of the operating statuses of the intelligent power supply apparatus 1 include but are not limited to the input voltage/current of the power converting circuit 11, the output voltage/current of the power converting circuit 11, the operating temperature, the fan's rotating speed, and so on. The operating status processor 14 is electrically connected to the sensors 12 and the audio processor 13. The storage unit 15 is electrically connected to the audio processor 13 and/or the operating status processor 14 for storing therein audio data and/or application programs. The audio processor 13 is used for converting/decoding digital input audio data into output audio signals or converting/encoding audio signals into digital input audio data. In response to the sensing signals, the operating status processor 14 controls the audio processor 13 to generate corresponding output audio signals. The loudspeaker 16 is electrically connected to the audio processor 13 for generating audio prompts corresponding to the output audio signals.
In this embodiment, the storage unit 15 is electrically connected to both of the audio processor 13 and the operating status processor 14. The storage unit 15 includes a memory and a memory access (not shown). An example of the memory of the storage unit 15 includes an EEPROM (Electrically Erasable Programmable Read-Only Memory), a flash memory or a ROM (Read-Only Memory).
By detecting operating statuses of the intelligent power supply apparatus 1, the sensors 12 issues corresponding sensing signals. In this embodiments, the sensors 12 includes an input voltage/current sensor 12 a , an output voltage/current sensor 12 b , a temperature sensor 12 c and a rotating speed sensor 12 d for sensing the input voltage/current of the power converting circuit 11, the output voltage/current of the power converting circuit 11, the operating temperature and the fan's rotating speed, respectively. The input voltage/current sensor 12 a and an output voltage/current sensor 12 b are respectively arranged in the input end 11 a and the output end 11 b of the power converting circuit 11. In receipt of the sensing signals, the operating status processor 14 will discriminate whether the intelligent power supply apparatus 1 has a malfunction such as abrupt voltage increase of the input voltage Vin, abrupt increase of the current inputting into the power converting circuit 11, an abrupt voltage increase of the DC output voltage Vout, an abrupt increase of the current outputting from the power converting circuit 11, a very high operating temperature or a very low fan's rotating speed. If the malfunction occurs, the operating status processor 14 will control the audio processor 13 to read out corresponding audio data stored in the storage unit 15. The audio data are then converted or decoded into corresponding output audio signals by the audio processor 13. In response to the output audio signals, the loudspeaker 16 generates corresponding audio prompts. In some embodiments, the audio prompts generated by the loudspeaker 16 are warning prompts to notify the user of the malfunction of the intelligent power supply apparatus 1. The warning prompts have contents indicating for example “abrupt increase of the input voltage”, “abrupt increase of input current”, “abrupt increase of the DC output voltage”, “abrupt increase of the output current”, “a very high operating temperature” or “a very low fan's rotating speed”. The warning prompts will help the user to realize that the intelligent power supply apparatus 1 has a specified malfunction.
In this embodiment, the application programs stored in the storage unit 15 are executed by the operating status processor 14 in order to implement associated functions. Moreover, for implement different functions, the application programs may be modified. Moreover, in addition to the warning prompts, the audio prompts generated by the loudspeaker 16 are operating prompts indicating preset operating conditions of the intelligent power supply apparatus 1 even if no malfunction occurs. The operating prompts are periodically generated and have contents indicating for example “the operating duration from startup of the intelligent power supply apparatus”, “the present input voltage”, “the present input current”, “the present output voltage”, “the present output current”, “the present operating temperature” and “the present fan's rotating speed”. For example, the loudspeaker 16 may generate operating prompts “the operating duration from startup of the intelligent power supply apparatus is two hours” or the like.
In some embodiments, the intelligent power supply apparatus 1 further comprises a communication interface 141. The communication interface 141 is communicated with an external processing device 17 such as a computer system or a motherboard of a computer system. Via the communication interface 141, the messages associated with the operating statuses, including for example the operating duration from startup of the intelligent power supply apparatus, the present input voltage, the present input current, the present output voltage, the present output current, the present operating temperature and the present fan's rotating speed, will be transmitted to the external processing device 17. As a consequence, the messages associated with the operating statuses may be shown on a monitor of the external processing device 17 or issued by another loudspeaker of the external processing device 17 in real time. Furthermore, the audio data stored in the storage unit 15 may be refreshed by the external processing device 17 through the communication interface 141.
